Obacunone 17-O-beta-D-glucoside
IUPAC 名称
9-[furan-3-yl({[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy})methyl]-5,5,7a,9,11b-pentamethyl-3,7-dioxo-5,5a,6,7,7a,9,10,11,11a,11b-decahydro-3H-spiro[naphtho[2,1-c]oxepine-8,2'-oxirane]-3'-carboxylic acid
描述
Obacunone 17-o-beta-d-glucoside is a member of the class of compounds known as limonoids. Limonoids are highly oxygenated, modified terpenoids with a prototypical structure either containing or derived from a precursor with a 4,4,8-trimethyl-17-furanylsteroid skeleton. All naturally occurring citrus limonoids contain a furan ring attached to the D-ring, at C-17, as well as oxygen containing functional groups at C-3, C-4, C-7, C-16 and C-17. Obacunone 17-o-beta-d-glucoside is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Obacunone 17-o-beta-d-glucoside can be found in lemon, mandarin orange (clementine, tangerine), and sweet orange, which makes obacunone 17-o-beta-d-glucoside a potential biomarker for the consumption of these food products.
